Investigation On The Energy Development Stratagem And The Energy Efficiency Of Chongqing City

Based on the 2010 GDP goal (double than 2000 year's) and the economical increase velocity( up 9 percent every year than last year during tenth five-years plan). And considering to improving the environment quality and keeping the stable social, the demand energy total quantity, the component in the demand energy, and the relationship between the energy consumption and the environment capability are forecasted for the tenth five-years plan, eleventh five-years plan and twelveth five-years plan of Chongqing City, with the expert forecast analytical method and ANSWER MARKAL energy optimum calculated software. And the same time, the energy development stratagem of Chongqing City is presented and the stratagem assume for ensuring the energy provide system, the energy being clean used method and the reconstruct traditional produce energy means are also provided. Therefore, it can make the following conclusions:In the case of the mix of the total energy demand, the coal, electricity, natural gas and oil will account for 63.73%, 12.40%, 14.62%, 9.25%; 57.07%, 14.35%, 17.86%, 10.71%; and 53.54%, 15.16%, 19.71%, 11.60% in 2005, 2010, and 2015, separately. In Chongqing, the rich energy resources have supported the sustainable economy development. As completing the new energy projects according to the plan, the primary energy production has increased greatly, it has optimized and adjusted the production structure, the share of coal has reduced, and that of clean energy (natural gas and hydropower) has risen considerably.For supporting the stable development of Chongqong's society and economy, Chongqing's total energy demand must increase greatly梚t will grow by 36.05%, 66.15%, and 109.45 % in 2005, 2010, and 2015 than that in 2000, respectively. That requires Chongqing Municipal to make preparation on energy production, exploiting, supply and investigation and carrying out of the relevant planning as soon as possible, to strengthen the macro control on energy production and supply, and to decrease the dependence on energy, and to open up reliable channels buying energy from other areas.. And it must lower the elasticity coefficient of energy consumption, and keep the sustainable development between energy, economy, and environment by strengthening industrial structure adjustment, raising the share of the tertiary industry in the national economy and the high added-value industry with low energy consumption in the industry.During 2005 and 2015, the coal will remain the main part of the energy production and consumption in Chongqing. But the share of electricity and natural gas will rise gradually, and the share of coal will decrease to 55% from the current 70%. It is necessary for controlling SC>2 emission to strengthen carrying out the strategy of clean coal. The share of natural gas will rise to 20% from 12% gradually. That will contribute to energy efficiency and environment improvement, but increase the cost for energy consumption.The results would play an important role in supporting the economical rapidly growth, increasing the efficiency of the energy, improving environment quality and accelerating harmonious & continuance development among the energy, economical and environment.
